HATTIE FAULKNER, OF INDIANAPOLIS, INDIANA, ADMINISTRATRIX GEORGE S.FAULKNER, DEOEASED' ST EAM-ACTUATED VALVE.

SPECIFICATION forming part of Letters Patent No. 434,080, dated August12,1890.

Application filed May 24, 1890- Serial No. 352,994. (No modelli- To allwhom it may concern:

Be it known that GEORGE S. FAULKNER, deceased, during his lifetime acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, did invent certain new and usefulImprovements in Steam-Actuated Valves, of which the following is aspecification.

The object of said invention is to procure a valve which will beautomatically operated and which will be simple and inexpensive inconstruction.

Said invention relates to that class of valves which are especiallyadapted for use with steam-pumps.

It consists in formingin a cylindrical valve (which fits closely withinasteam-chest transversely and extends nearly throughout its entirelength) such a series of ports as will enable it not only to deliversteam to the main cylinder, but to itself, thus constituting it initself substantially a piston, whereby the ports which extend through itare opened and closed.

The peculiar construction of this valve and, the number and arrangementof the ports therein will be hereinafter more particularly described andclaimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a top or plan view of a steam-pump provided with said invention;Fig. 2, a side elevation of the same; Fig. 3, a longitudinal verticalsectional view, looking toward the left from the dotted lines 3 3,through the steam-chest valve and immediately adjacent parts, on anenlarged scale; Figs. 4, 5, 6, and 7, transverse vertical sectionalviews looking toward the right from the dotted lines 4 4, 5 5, 6 6, and'7 7, respectively, in Fig. 3; Fig. 8, a fragmentary longitudinalsection on the dotted line 8 8 in Figs. 4 and 5, showing the by-paths inthe body of the steam-chest cylinder and the depressions and orifices inthe valve at one end, which constitutes the valve construction, wherebysaid cylinder or main valve is itself operated; Fig. 9, a similar viewof the corresponding parts at the other end on the dotted line 9 9 inFig. 7; Fig. 10, an under side plan of the valve separately, and Fig, 11a plan of the entire surface of the valve asit would appear if flattenedout.

In said drawings, the portion marked A represents the pump; B, thesteam-cylinder by which it is operated; C, the steam-chest; D, thevalve, and E a transverse shaft by which said valve is given a slightrocking motion during the operation of the pump, as will be hereinafterexplained.

The pump A-and main operating-cylinder B are, or may be, of any usual ordesired construction. They are not peculiar to the present invention,and therefore will not befur ther described herein, except incidentallyin describing the invention. The piston-rod B extends from one to theother, as is usual in pumps of this character, and secured to this.

piston-rod is an arm B by which, through suitable connecting rods andarms, one of the operations of the valve is effected, as will presentlybe more fully described.

The steam-chest or valve-cylinder O is, as shown, cylindrical in formand contains the valve D, which, as before stated, is substantiallyequal in size to the internal diameter of this cylindrical steam-chest.In addition to the usual construction there are several by-paths c c c 0formed in the wall of this steam chest or cylinder, (constituting, withcorresponding openings in the valve, ports for operating said valve,)through two of which live steam passes to the ends of the valve, andthus operates it, and through the other two of which said steamexhausts. As in ordinary steam-engine Work, the live-steam port orby-path at one end is in operation while the exhaust-steam port orby-path on the opposite end is in operation. A convenient means offorming these by-paths or ports is to drill in from the ends of thecylinder the required distance and then drill through transversely intothese ports ateach end. The ends of these openings will then be coveredby the cylinder-heads when placed in position, and therefore the littlespaces between the nearest transverse holes and the cylinder-heads(shown in Figs. 8 and 9) are useless except as a convenience in makingthe machine. In large machines these openings may be better cored out.In Verysmall machines it may be necessary to drill through from theoutside of the cylinder, especially at the inner ends'of these openings,and then plug the holes on the outside. This is also shown in thedrawings, (see Fig. 5;) but it will be understood, of course, that theseare mere mechanical expedients and are not essential to the invention. Alive-steam pipe 0 is shown as coming in at the top of this steam chestor cylinder, and an exhaust-steam pipe B is shown as leading from theside of the main cylinder B near its top. The valve D at its extremeends is a solid cylinder. Interiorly it contains a chamber D,which'terminates in the live-steam. ports 19, and a chamber D the endsof which are exhaustports at. An opening 0 extends up through its topfrom the chamber D and communicates with the live-steam pipe 0, as shownmost plainly in Figs. 3 and 6. This opening is larger than the pipe, inorder that the communication may always be free, notwithstanding themovement of the valve. So far as the live-steam and exhaust ports areconcerned, they are'simple and easily understood to any one familiarwith such matters.

Centrally at the bottom side and extending into the chainberD is a slitS of the form shown most plainly in Figs. 10 and 11, the diagonal ends 8s of which come in contact with the arm e on the shaft E, hereinafterdescribed, whereby this valve is rocked somewhat from side to side, aswill be presently explained. In the outer surface of this valve D arelong narrow depressions, as shown most plainly in Figs. 10 and 11, whichterminate in holes (1, d 02 and (1 extending through the shell of thevalve into the chambers D D and which correspond with the by-paths c c cc, and, with said by-paths, form small ports and valves by which thelarge or main valve D is itself operated. Two of these holes d (1 one ateach end, extend through into the live-steam chamber D, while the othertwo d d extend through into the exhaust-steam chamber D Small notches dand d are cut in the extreme ends of the valve, on the corners thereof,and in line with the holes (1 d, for the purpose of affording a morecertain ingress for the live steam into the space behind the ends of thevalve, when said valve is at its extreme position nearest the heads ofthe steam-chest. Now supposing that the valve D is turned so that thehole (1 registers or is in line with the inner hole leading into theby-paths c, it will be apparent that a small amount of live steam willpass from the live-steam chamber D by way of the correspondingdepression con nected therewith, through this hole and this by-path tothe end of the valve, between it and the head of the steam-chest, whichwill have the effect to force the valve toward the other end of thesteam-chest. When the valve has nearly reached the end of its stroke inthe other direction, the diagonal slot in the underside comes in contactwith the arm e on the shaft E, carrying the valve and throwing the holed (or its depression) and the hole or by-path 0" out of registry, atthe'same time throwing the hole (1 (or its depression) and the hole orby-path 0 into registry. The exhauststeam openings d c are also broughtinto registry, and thoseviz., d c which were before in that conditionare thrown out of registry or cut off, and this operation is continuallyrepeated. Itwill be observed that this rocking inder, and as a part ofsaid ports, but also as live and exhaust steam ports for itself.

The shaft E passes transversely through the downwardly-projectingportion cast on the under side of the steam chest or cylinder, and hasmounted thereon an arm e, which extends up into the diagonal slot in theunder side of the valve. This arm is securely and fixedly mounted onsaid shaft, as shown most plainly in Fig. 5. At the outer end this shaftis connected to an arm E, which in turn is connected by a connecting-rodE to the arm B on the main piston-rod B. This is sov adjusted that themotion throws the arm into exactly the position which it is required forproperly operating the valve. The arm E is preferably connected to theshaft E by means of a quadrant E and by means of this quadrant, as willbe readily understood, any degree of adjustment may be effected, and theadjustment may be varied so that the valves formed by the holes d, &c.,and their depressions, and the by-paths c, &c., may be thrown into orout of operation at varying periods, and the travel of the valve thusregulated. The arm 6 by this movement (which is given it through therock-shaft E, which in turn is driven from the piston-rod) operates toshift the valve more promptly than if it were stationary. Having thismovement, it also permits the diagonal slot to be larger than if it werestationary, admitting of a greater range of adjustment. There isanadjusting-slot in the arm E at its lower end, where it connect-s to therod E, as shown most plainly in Fig. 6, and thus the distance throughwhich the rock-shaft and consequently the arm 6 moves can also becorrectly adjusted. A bolt a having a thumb-nut thereon, is thepreferred means of connecting the quadrant E and the arm E while acenter-head bolt, having a nut on its outer end, is the preferred meansof connecting the arm E and the connecting-rod E all as shown mostplainly in Fig. 6.

Having thus fully described the said inven IIO tion, what is claimed asnew, and desired to be secured byLetters Patent, is-- 1. In combination,a cylindrical steamchest provided with the ordinary ingress pipe andports, and a cylindrical valve of the same diameter as the internaldiameter of the steamchest, but of somewhat less length, and providedwith live and exhaust steam chambers, and a series of openings andby-paths in the shell of the steam-chest and in the valve, a diagonalslot also in said valve, and an upward projection or arm adapted toengage with said slot, whereby as said valve is reciprocated by theaction of the steam it is also rocked by means of said arm or projectionand a different set of perforations and bypaths brought into registry,substantially as set forth.

2. The combination of a cylindrical steamchest provided with fourlongitudinal perforations, two at each end, one of each of which isadapted to receive live steam and the other to permit the escape ofexhaust-steam, a cylindrical valve fitted within said steam-chest andprovided with a live-steam and an exhaust-steam chamber, depressions inthe surface of said valve, and perforations extending from saiddepressions through into saidchambers, said depressions being arrangedto register with the holes leading into the bypaths in the steam-chest,whereby a small amount of steam may be conducted through saiddepressions and openings and by-paths to the end of the valve and saidvalve thussaid valve and connected to the mechanism A of the engine andcarrying an arm which extends up into said diagonal slot,'said shaftbeing adapted-to be rocked oppositely to the motion of the valve andsaid arm thus operated to shift the valve more promptly, substantiallyas set forth.

4. The combination of a cylindricalvalve having supplementary ports,whereby it is itself operated, a diagonal slot therein, a rockshafthaving an arm whereby said valve is rotated, a quadrant on the shaftcarrying said arm, and an arm adj ustably connected to said quadrant andalso connected to the moving .part of the machine, whereby the movementof said shaft and of the arm engaging with the valve may be adjustablydetermined, substantially as set forth.

5. The combination of a cylindrical steamchest having longitudinalperforations or bypaths extending in from its ends parallel with thevalve-opening therein, said by-paths communicating at either end withsaid valve-opening, and a valve fitted in said valve-opening andprovided with a live-steam chamber and an exhaust-steam chamber, andhaving longitudinal depressions on its outer surface adapted toalternately register with the openings communicating with said by-paths,and means whereby said Valve may be rocked to cause the ports ordepressions in its surface to alternately register first with one set ofbypaths and then with the other, substantially as described, and for thepurpose specified.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 21st day of May, A. D. 1890.
